Abstract

PURPOSE:To improve the conveying power of magnetic powder by magnetizing the conveying path or spiral rolls of a magnetic powder conveyor consisting of the conveying path for the magnetic powder and the spiral rolls disposed apart at a spacing in which the magnetic powder can be conveyed along the conveying direction of the conveying path. CONSTITUTION:Magnetic material members 90a, 92a are disposed along the axial direction of the spiral rolls 90, 92 on the rear side of lower parts 89a, 91a of toner recovering vessels 89, 91 and the spiral rolls 90, 92 are magnetized. Conductive magnetic toners 72 scraped by toner scraping members 79a, 79b, 84 from the surfaces of sleeve rolls 77, 78, 82 are attracted to the spiral rolls 90, 92 and are efficiently conveyed to toner stacking parts 89b, 81b. The toners 72 are attracted to the toner conveying surface of toner conveying belts 93, 94 and are conveyed onto a toner stacking part 61a on the sleeve roll 70. The conveyed toners are scraped by toner scraping members 93f, 94f.
